This is the cheapest I've found, once delivery is included - unless anyone can advise otherwise?

Many thanks for the tip - it's sorted one but the other appears dead, so a new one (or possibly 2, bearing in mind postage costs being the same for 1 or 2, and they're only 20 quid each anyway) is needed.

Many thanks; the zone type is described as "Normally closed loops which activate when opened or connected to 0 volts from dc power supply" - nothing about double pole though?

Hi,
I have a couple of Pyronix Equinox E dual tec PIR's that have been great; however I'm now finding that they are becoming less sensitive during walk test (but no false alarms though). In fairness they're 20+ years old....
Is such behaviour the norm, and if so I've been looking at Pyronix KX15DT's - are these a worthy replacement?
One last question - the Equinox E states a relay contact via a 4.7 ohm series resistor, yet the KX15DT incorporates selectable alarm resistor values of 6K8, 5K6, 4K7 &1K & tamper values of 5K6, 4K7, 2K2 and 1K. So what should I select? My panel tech spec. quotes a "Zone Activation Resistance" of 2Kohms (minimum)" if that's of help.
Many thanks in advance

Hi,
My Bellbox (circa 1993) works fine, though I've not tested the SAB Module for longer than I can remember. Bearing in mind it's 20+ years old, the (Nicad?) battery on the SAB ( a standalone PCB) is likely to have had it (or certainly long past it's best!).
My question is: are such Modules still available, or are they all integrated into complete bell box assemblies nowadays? I've tried a Google search, but without success. Many thanks.
